Serial No. 634,711. 1

To all whomtt may concern:

Be it known that I, ERIC R. LUNDIUS, a citizen of the United States,residing at Seattle, inthe county of King, State of Washington, haveinvented certain new and useful Improvements in Book-Holders; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to new and useful improvements in .book holders andmore especially to that type of book holder adapted to hold the book ineither closed or open position as desired, and the object of myinvention is to improve'the construction and increase the efficiency ofbook holders of.

the above described character.

A further object of my invention is to provide a book holderin which thebook may be held at any desired angle, thereby facilitating the readingthereof.

A further object of my invention is to provide a book holder in whichthe book when closed is in ,a normally vertical position and in whichthe tilting of the book to bring it to the desired angle at the sametime causes the opening of the book.

A further object of my invention is to provide a holder in which theswinging of the book out of operative position automatically closes thebook. And a still further object of my invention is to provide a bookholder which will always open the book at the same page.

With these and other objects in view, my invention will be more fullydescribed, illustrated in the drawings which show a preferred embodimentof my book holder and then specifically pointed out in the claims whichare attached to and form a part of this application.

In the accompanying drawings :Figure 1 is a side elevation of thedevice, closed. Fig. 2 is a side elevation of the device open andshowing the releasing hook in operative position, in dotted lines. Fig.3 is a front view closed. Fig. 4: is a section on the line 1-4 ofFig. 1. Fig. 5 is a detail section on line 55 of Fig. 1. Fig. 6 is adetail view of the hook. Fig. 7 is a detail view of the handle.

Referring more specifically to the drawings in which similar referencenumerals designate corresponding parts throughout,

vided with an outwardly and downwardly extending spindle member 3adapted to be seated in the socket 4 of a swivel bracket 5 which issecured by screws 6 to a wall, desk or other preferred support 7. Thisspindle is provided intermediate its length with an annular groove 8adapted to be engaged by the inner end of the set screw 9 which ispassed through the side wall of the socket, whereby the body 1 is freeto rotate upon the bracket but is held from disengagement therefrom. Theopposite side of the head member 2 extends beyond the body member properand the book rest proper, which as a whole is designated by the numeral10, and I is secured by its upper end to the lower portion of the outerface of the head by means of a hinge 11, the upper end of the book rest10 being beveled as shown at 12 to permit the same to be raised to anydesired angle in respect to the body member 1.

Secured to the upper portion of the outer face of the member 10 is anoutwardly and upwardly extending ratchet sector 13 having a plurality ofdownwardly inclined ratchet teeth 14: formed upon its outer face, whichis arcuate in shape, said teeth being adapted to be engaged by a hook 15which is pivotally mounted between upstanding ears 16 formed in theupper forward portion of the head member 2. An arched leaf spring 17 issecured by a screw or other suitable means 18 to the upper rear portionof the head member in such a manner that its free end rests upon theupper face of the hook 15 at a point slightly in advance of the pivotalpoint thereof, whereby the hook is maintained in engagement with theteeth. As shown the pivotal portion of the hook is provided with anoutstanding shoulder 19 which bears against the outer face of the head 2when the hook is in lowered position thereby limiting its downwardmotion, by

which means the hook is at all times maintained in position to engagewith the teeth of the sector. The forward face of thehook and the upperface of the sector member are curved as shown in such a manner as topermit the'sector member to readily slide under the hook and be engagedthereby.

From the above it will be readily understood that the supporting member10 may be swung outwardly to any desired angle and held in adjustedposition by means of the hook and sector above described.

The rear face of the supporting member 10 is provided intermediate itslength with a pair of rearwardly extending spaced apart ears 20 andpivotally mounted between these ears is a release rod 21 the upper endof which is bent outwardly and passed through a suitable aperture 22formed in the supporting member 10 at a point adjacent the sector member13 to which it is secured by means of the U-shaped clip 23, said endterminating as shown at a point slightly in advance of the sector member13. The clip 23 and the aperture 22 are so proportioned that theforwardly extending end of the release rod is slidable therethrough anda leaf spring 24 is secured by one end to the upper portion of the rearface of the supporting member 10 by a screw 25 in such a manner that itsfree end bears against the release rod and serves to maintain the samenormally in withdrawn position as best shown in Fig. 1 of the drawings.Secured upon the upper face of the hook member 15 is a plate 26 whichextends beyond the free end of the hook as shown at 27 and one side ofwhich as shown at 28 extends beyond the side of the hook 15 and is bentdownwardly to form a depending flange 29 parallel to and spaced apartfrom the side of the hook, the purpose of which plate will behereinafter fully explained.

The lower end of the release rod 21 extends downwardly and terminates ata point adjacent the lower end of the supporting member 10, at whichpoint it is pivotally mounted in the slotted end 30 of a handle 31, thepivotal point being intermediate the length of the handle, whereby theupper end of the handle extends upwardly between the members 1 and 10while the lower end extends below the same a suflicient distance to beeasily grasped by the operator. Adjacent the upper end of this handlethe rear face of the supporting member 10 is provided with atransversely extending notch 32 the purpose of which will be hereinafterexplained.

Extending through a suitable aperture formed in the lower end of thesupporting member 10 is a screw 33 upon the threaded end of which is awing nut 34. As shown the head portion of the screw is spaced at aslight distance in advance of the forward face of the member 10 andforms the ball member 35 of a gimbal joint 36 the socket member 37 ofwhich is formed at one end of a rod 38 the other end of which terminatesin an eye 39 adapted to engage over the free end of a screw 40 whichextends outwardly through the lower portion of the sector member asshown, a wing nut 41 being supplied to maintain the same in position. Infastening the book to my improved holder the upper end of the rod 38 isreleased and the rod swung outwardly upon the gimbal joint as a pivot,said rod is then inserted, between the leaves of the book to be securedand which is conventionally shown at 42, the rod 38 is then swung backinto position and secured in place by the wing nut 41 ,thus firmlyclamping the book against the outer face of the supporting member 10 andit will be readily understood that by means of the screws 33 and 40 andthe wing nuts 34 and 41 the clamping rod may be adjusted to secure anyform of book irrespective of the style of binding.

Secured transversely across the rear face of the supporting member 10 ata point intermediate between the ends of this clamping rod is a plate 43the ends of which extend upon either side beyond the sides of the member10 and hinges 44 and 45 are secured by one end between the member 10 andthe plate 43 by the same screws 46 which secure the plate 43. Secured tothe free ends of the hinges 44 and 45 are outwardly extending wings 47and 48, which as best shown in Fig. 5 of the drawings are bowedoutwardly intermediate their length and then inwardly in such a mannerthat their free ends are adjacent each other when the wings are swungtogether. Secured to the side edges of the body member 1, one uponeither side thereof are substantially U- shaped closing rails 49 and 50,the function of said rails being to normally maintain the wings 47 and48 in closed position.

In operation the handle 31 is grasped by the operator and the supportingmember 10 swung outwardly thereby upon the hinge 11 until the book is atthe desired angle, the ratchet sector 13 in the meantime passing beneaththe hook 15 while the upper end of the release rod 21 passes between thehook 155 and the flange 29 of the plate 26. hen the book has been swungto the required angle the handle is released, the hook 15 serving tomaintain the supporting member 10 and consequently the book in adjustedposition. In the meanwhile as soon as the bowed portion of the wings 47and 48 have passed beyond the control of the closing rails 49 and 50they swing outwardly causing the book to automatically open at the pagesbetween which the clamping rod 38 is inserted. In practice the book isusually swung outwardly at such an angle that the supporting wings 47and 48 extend at right angles to their normal position and when soextended the extending ends of the plate 43 serve to limit their furtheropening whereby the wings serve to support the sides of the book in itsopen position. When the book is to be closed, the handle 31 is pressedinwardly, its upper end engaging with the notch 32 to form a fulcrumwhereby the upper end of the release rod 21 is forced through theaperture 22 and the clip 23 against the force of the spring 24 until itsfree end presses upwardly againstthe plate 26 in such a manneras toraise the hook 15 against the force of the springs 17 to release theratchet sector, when it will be readily understood the supporting member10 may be swung back into normal position against the body member 1. Asthe supporting in operation. By means of the interaction of the wingsand closing rails the mere swinging of the book to aconvenient angle forreading serves to open the book while the swinging of the book back toposition serves to close the same.

The above described holder may of course be used to advantage with anybook desired but is especially intended for use with ref erence bookssuch as dictionaries and directories, and when used with the latter isof particular value owing to the fact that it always opens the book atthe same place,

thus when using the telephone directory the rod may be positionedbetween the pages containing the list of local subscribers thus insuringthe correct opening of the book at all times. For use in pay stationsand the like in stores the rod may be positioned between the pagescontaining the owners advertisement, which as will be easily understoodis of great advantage and tends to greatly increase the value of thatform of advertisement.
